Specification of Letters IPatent.

Patented .rune 15, 1909.-

Application led August 26, 1908. Serial No. 460356.

YTo all whom 'it may concern: Y

' composition upon its surface adjacent to the outer cover of horse-hideor similar material.

As4 heretofore constructed, the centralV resilient sphere or core ofbase balls has been formed of solid india rubber, having layers of yarnwound thereon.

The object of my invention is to produce a f playing ball of saidclasshaving a resilient central core that is yless yielding than hasheretofore been made upjon which the layers of yarn may be wound undergreater tension, whereby greater compactness resultshperfect concentricformationis attained, and a more durable and rigid structure secured anduniform resiliency acquired and maintained.

A further object of my invention is to provide a central spherical coreof cork ors1milar material incasedA tightly in a layer of india rubberupon which strands of yarn may be wound. I

To these ends my invention includes the combination and arrangement ofcomponent parts to be hereinafter described and more particularlypointed out in the claims.

In the accompanying drawings, in which' "cased in a layer of rubber,layers of yarn or similar'thread tightly wound thereon, a layer ofadhesive plastic composition upon the outer surface of the yarn, and acover of 'horse-hide or similar material incasing the same.l

Referring now to the drawings, 1 designates my central spherical core,which comprises a center of cork 2 or similar resilient material that isless yielding than rubber tightly incased in a layer of india rubber 3.Upon said -central sphere is tightly wound a layer of thread 4,preferably `of woolen yarn. The saidlayer of thread is held in itsspherical contour by a layer of adhesive plastic composition 5, whichmay be surrounded by a layer of threadfl and the whole structure lisincased in an outer cover 6, preferably of horse-hide stitched thereon.

As more clearly shown in Fig. 2 of the drawings, the layer of rubber 3incasing the 'cork center 2 comprises rubber threads vor rubber tapewound thereon. Said threads or tape may be of adhesive rubber, or stripsof web fabric saturatedor coated with an or similar material may beused, in the winding of either; of which, the tension thereof `may beregulated to modify the degree of resiliencyof the ball.

From the foregoing description, it will be apparentthat the structure ofthe central -core will permit a greater tension and more compact windingof the adjacent layer of thread or yarn, thereby producing a more rigidconstruction of the entire ball, with resultant increased strength anddurability and uniform concentric structure and resiliency, andfurthermore permitting the making of balls of more uniform Weight andsize than has heretofore been possible when built upon ayielding core ofirregular contour. i

ter of solid cork, layers of resilient rubber strands wound thereon,layers of thread Wound upon saidlayers, and an outer cover incasingsame, substantially as described.

2. A. base ball comprising a spherical center of solid cork, layers ofadhesive resilient rubber strands wound thereon, layers of thread woundupon said layers, and an outer cover incasing same, substantially asdeiscribed. 'i

In testimony whereof, I have hereunto signed my name to thisspecification in the 4presence of two subscribing witnesses.
